Chapter 25, Problem 6P

25.1 and 25.2 Polarization of waves and Discovery of electromagnetic waves

One dipole antenna points in the x-direction and the other identical antenna points in the y-direction. The currents in the antennas oscillate in phase and with the same frequency. Determine the angle between the x-axis and the direction of oscillation of the $\stackrel{\to }{E}$ field and $\stackrel{\to }{B}$ field at a point on the z-axis, far from the antennas.
